View Full Version : White flashing line on the right side of video

Hi,
I've been using the new Xvid 1.0 builds for a while now.
I especially like the way the zoning was designed.

There is only one problem that arises every now and then, though I'm not sure if it is an Xvid/Avisynth or Vdubmod related.

There is a white flashing line that appears on the right edge of some videos that I encode. It only occurs on a B-frame or GMC frame.

I use resolutions that are mod 32.

I'm not sure if this occurs because of the color space conversion I use in Avisynth. ie. the use of converttoyv12()

It is often the case that if I re-encode the same avisynth script using Xvid, sometimes the white line is eminent and other times it doesn't appear.

The Source i use is captured in MJPEG which is in Yuy2. So I use converttoyv12() in avisynth in order to use convolution3d.

This is what the avs script i use normally looks like

LoadPlugin("D:\Appz\Video.Encoding.Editing.Playback\Gordian Knot 0.28.6\Gordian Knot\mpeg2dec3.dll")
LoadPlugin("D:\Appz\Video.Encoding.Editing.Playback\Gordian Knot 0.28.6\Gordian Knot\undot.dll")
LoadPlugin("D:\Appz\Video.Encoding.Editing.Playback\Gordian Knot 0.28.6\Gordian Knot\Convolution3d.dll")
LoadPlugin("D:\Appz\Video.Encoding.Editing.Playback\Gordian Knot 0.28.6\Gordian Knot\FluxSmooth.dll")
# SOURCE
avisource("C:\mbc variety game show (korean).avs")
# CROPPING
crop(0,0,638,476)
converttoyv12()
lumafilter()
Undot()
Convolution3d("movielq")
# RESIZING
LanczosResize(512,384)
undot()
fluxsmooth(5,7)


I haven't tried using Divx because it looks too complicated to use.

Thanks for the Xvid builds.

Hmmm. I have this line too, but only when video is resized...
I thought, it was a resizer problem ?

crop to mod4 resolutions. (i.e. 636x... or 640x...)

moved to avisynth forum because this is a script error, not an xvid bug.

Yep. Tested. That is.
Thanks, Koepi !

This problem has been bugging me for some time now. I could never figure out what was wrong. Hopefully it should be resolved.

I'll give it a try next time.

Thanks Koepi
